Abstract (en)

[origin: US2021250772A1] Sidelink (SL) resource selection includes determining that all SL resources within an SL resource pool for an SL resource selection window are unclaimed for SL transmission when no prior sensing results are available for an SL channel, and determining which SL resources within the SL resource pool are unclaimed for SL transmission based on the prior sensing results when prior sensing results are available. Unclaimed SL resource(s) are randomly selected, and the SL channel is sensed during one or more slots preceding the randomly selected SL resource(s) to determine availability before transmitting on or signaling the randomly selected SL resource(s). Transmission on a first-in-time of the randomly selected SL resource(s) is based on the availability determination and, in the first-in-time randomly selected SL resource, one or more additional SL resource(s) are signaled based on the availability determination.
